Fig. 1. Comparison of the normalized differential coefficients. Dashed line: KlO and K tO from the traditional formulae, solid line: KlN and KtN from the new formulae
Fig. 2. Photos of experiment site. (a) Sub-aperture mask of mini DIMMprototype; (b) Mini DIMM prototype (left) and standard DIMM (right) measuring simultaneously
Fig. 3. Comparison of the longitudinal and transverse atmospheric coherence length. (a) r 0l 、r 0t calculated by the traditional formulae from miniDIMM; (b) r 0l 、r 0t calculated by the new formulae from miniDIMM. r 0l 、r 0t from standard DIMM minus 4 are also shown in the figure (the bottom lines) for comparison
